Definitions
- the invention is based on a sealing arrangement for pneumatic directional valve according to the in the preamble of Claim 1 specified genus.
- This Directional control valve consists of a housing with inlet, return and Working channels in which a valve spool can move longitudinally is guided in a slide hole.
- This valve spool has cylindrical piston sections and intermediate, sleeve-shaped couplings of smaller outer diameter.
- sealing bodies In Grooves of the piston sections are arranged sealing bodies, that interact with the change of the slide bore if necessary, a mutual sealing of the channels allow. In practice, it occurs particularly with one slow switching of such a directional valve under maximum air flow that the sealing body from their Groove pushed out and as the movement of the Valve slide pinched off on the housing-side edges become.
- the damage caused to the Sealing bodies can cause total failure of the directional valve cause.
- the pushing out of the groove is triggered by an abrupt sealing of a pressure medium connection between two channels, connected with one that takes place abrupt pressure increase on a flank of the sealing body.
- the known directional control valve specially shaped sealing body provided. These keep short before the final sealing of the pressure medium connection recesses free between two channels, via the one extensive pressure equalization can take place.
- a external sealing system is the structure of the valve spool relatively complex, because a variety of ring grooves Inclusion of the sealing body is to be provided.
- the Seal assembly is done manually.
- the Slider bore made with high surface quality to ensure optimal operating conditions for the seals to ensure. All of these measures lead to them a directional valve with such a sealing arrangement expensive.
- a pneumatic directional control valve is known from DE 100 076 87 A1 known with a generic sealing arrangement.
- this directional control valve has the housing in its Walls delimiting the slide bore housing gaps, into those interacting with the spool Sealing rings are used.
- the Sealing rings in the radial direction through webs fixed to the housing held and in the axial direction by hollow box-shaped Insert body fixed radially to the spool built into the housing between the fixed webs are.
- Specially designed sealing rings with the outer contour an eight, in which an outer ring part with a web an inner ring part is connected in the Housing columns arranged.
- measures are to be taken Sealing rings provided to switch the Control slide a pushing out of the sealing rings or their To avoid damage.
- the inventive sealing arrangement for a pneumatic directional valve with the characteristic features the main claim has the advantage that it a cost-effective, internal sealing system enables that with a simple assembly also a ensures secure sealing, being pushed out or sucking the sealing rings out of the housing gap can be largely avoided. It can be by Sealing lips in a particularly simple manner a safe Achieve sealing.
- An embodiment according to claim 2 is particularly advantageous, when the seal assembly is self-centering in the housing is arranged so that straightness errors of Control spool or housing do not interfere.
- the seal can self-centering so that the Piston sections always uniform along the circumference Pressure occurs, which increases the overall friction of the Control spool in the housing can be reduced. Also This allows manufacturing inaccuracies in the housing balance more easily.
- the sealing arrangement is suitable therefore especially for directional valves that respond easily, one achieve a long service life and build inexpensively. It is also particularly advantageous to design the Sealing arrangement according to claim 3, whereby the Arranging the sealing ring with preload in the housing gap, so that it prevents being pushed out or sucked out Differences in pressure better during a shift is secured. It is also advantageous that Execute sealing arrangement according to claim 4 to the Air inlet or air outlet in the housing gap support and thus the danger of pushing out the Reduce sealing rings from the housing gap. Further advantageous configurations result from the rest Claims, the description and the drawing.
- Figure 1 shows in a greatly simplified Representation and a partial section on an enlarged scale through a pneumatic directional valve with a sealing arrangement according to the invention and Figure 2, as Detail on an enlarged scale, a cross section through the sealing ring according to Figure 1.
- Figure 1 shows in a simplified and enlarged form a longitudinal section through part of a directional control valve 10 with the sealing arrangement according to the invention 11. From the directional control valve 10 shows only a part and this part as far as explained to understand the Sealing arrangement 11 is required.
- the directional control valve 10 has a housing 12 through slide bore 13 in which a longitudinally movable control slide 14 sliding and sealed is led.
- a first chamber 15 through the seal assembly 11 from a second chamber 16 separately, with an inlet channel 17 in the first chamber 15 and an outlet channel 18 opens into the second chamber.
- Housing 12 runs between the channels 17, 18 Housing gap 19 which penetrates the slide bore 13 from flat, mutually parallel walls 21, 22 is limited, and has an external connection through an opening 23.
- Housing gap 19 is through the opening 23 from the outside forth the transverse to the slide bore 13 Sealing arrangement 11 installed. From the spool 14 is in Figure 1, only a piston section 24 with a adjacent, bolt-shaped web part shown. In the shown position of the control slide 14 it penetrates with its cylindrical piston section 24 the Seal assembly 11, whereby the first chamber 15 from the second chamber 16 is sealed off.
- the sealing arrangement 11 built in two parts.
- the sealing arrangement 11 is made from an external retaining ring 26 and the actual in the retaining ring 26 arranged sealing ring 27.
- the retaining ring 26 consists of a dimensionally stable material, whereby this e.g. can be a metal or a dimensionally stable plastic.
- the retaining ring 26 is used, among other things, for the sealing ring 27 to install in the housing 12.
- the sealing ring 27, which is made of a suitable, relatively soft Sealing material is inserted into the retaining ring 26, who in this way the sealing ring 27 in his holds circular shape, its handling thereby simplified and its installation easier.
- the Retaining ring 26 is in the axial direction of the Control spool 25 executed so thick that it in the Housing gap 19 is performed with slight play, which for Example with conventional pneumatic directional control valves 0.2 mm can be.
- the housing gap 19 is so large executed that the retaining ring 26 also in the radial direction has a game 28.
- the dimensionally stable retaining ring 26 is thus in the housing gap 19 in the radial direction to the control slide running level essentially floating.
- the sealing ring 27 consists of an outer ring part 31 and an inner ring part 32, which by an annular web 33rd are interconnected.
- the sealing ring 27 is thus built in one piece and solid, the two ring parts 31 and 32 are concentric.
- the outer ring part 31 essentially has the basic shape of a isosceles trapezes, its short, parallel Forms an outer lateral surface 34 with which the Sealing ring 27 on the cylindrical bore 35 of the retaining ring 26 is present.
- the long side of the isosceles trapeze extends between projecting ribs 36, the Distance from each other is slightly larger than the distance of Walls 21, 22 of the housing gap 19, so that the built-in Sealing ring 27 in the housing gap 19 under a certain Preload is there.
- On the outer ring part 31 are also on the side facing the inner ring part 32, that is from the long trapezoidal side, in the area between the ribs 36 and the base 37 of the ring web 33 projecting obliquely outwards Sealing lips 38 arranged. These sealing lips 38, their free Length corresponds approximately to the thickness of the ring web 33, put with the built-in sealing ring 27 on the walls 21 and 22 and ensure a secure seal to the outside.
- these sealing lips 38 are shown in FIG shown undeformed state, so that its initial shape becomes more recognizable.
- the sloping legs of the trapeze, which end in the ribs 36 form side surfaces 40 am Sealing ring 27.
- the inner ring part 32 has one round basic shape and flattened parallel to each other Side walls 39, which also the walls 21 and 22 in Housing gap 19 are opposite. In these side walls 39 are evenly distributed radially along the circumference extending passage grooves 41 are arranged, via which at built-in seal assembly 11 a pressure equalizing Pressure medium flow in or out of the housing gap 19 take place can.
- a curved, smooth Contact zone 42 formed is formed, the configuration of which is preferred is adapted to the material of the sealing ring 27.
- the sealing ring 27 is symmetrical built up its middle plane; it is also preferred circular.
- the Sealing arrangement 11 In the operation of the pneumatic directional valve 10, the Sealing arrangement 11 once the seal between the two chambers 15 and 16, as well as the Sealing to the outside via the housing gap 19.
- the sealing ring 27 With the Position of the piston portion 24 shown in Figure 1, is the sealing ring 27 with its rounded, smooth and biased contact zone 42 on the outer diameter of the Slider and ensures the dynamic tightness. Due to the reduced thickness of the ring web 33, the Inner ring part 32 in a known manner in reinforced Measure the tightness function. About the Passage grooves 41 becomes the inlet and outlet of Air in the housing gap 19 allows, so the danger a pushing out of the sealing ring 27 from the Housing gap 19 when switching the control slide 14th is reduced.
- the sealing arrangement 11 enables space-saving and inexpensive design and is also easy to install; it can be used advantageously with multi-way valves, such as in a 5/2 switching valve, where several such seal assemblies 11 in a housing to be ordered.
